To overcome the dependence on use of reinforcing steel in concrete, alternative materials are used as reinforcement that is easy and cheap to obtain resistant corrosion namely rattan rods. With this material natural resources can be utilized optimally. This research uses for concrete beams. The test carried out using a two-point loading method, 4 types beams, 2 beam (BR ), 3 ) (BS control resul...

Abstract. The ability of solid structures to absorb a certain part the energy dynamic impacts has not been properly reflected in impact theories. Meanwhile effect material properties on various is so much that ignoring it when solution large number problems makes impossible explain without distorting quantitatively and qualitatively, many actually observed phenomena, for example, equalization s...

Concrete is the material which is rapidly used in various conditions to sustain the compression loads and the corresponding bending and shear stress due to the applied compressive loads. The major drawback in concrete is that it is poor in tension though it is very efficient in compression. Hence to overcome this major drawback the concrete must be reinforced such that to make a homogeneous sub...

Results of an experimental investigation on the behavior and ultimate shear capacity of 27 reinforced concrete Transfer (deep) beams are summarized. The main variables were percent longitudinal (tension) steel (0.28 to 0.60%), percent horizontal web steel (0.60 to 2.40%), percent vertical steel (0.50 to 2.25%), percent orthogonal web steel, shear span-to-depth ratio (1.10 to 3.20) and cube conc...

Concrete is usually highly alkaline (pH around 12), thus protecting reinforcement against corrosion. The occurrence of oxides is favored when the medium pH surrounding the bar is in values near to 9 or lower. Aggressive substances for reinforcements generally enter concrete through its pore structure, and cracks tend to decrease pH, stimulating corrosion process. There are several causes for cr...

Shape memory alloys (SMAs) are unique smart materials that have many advantages, such as ability to resist large strains without leaving residual strains and ability to recover original form. However, the high costs of SMAs have limited their usage. This paper evaluates the behavior of concrete structures equipped with SMAs in an optimal manner as they are being used along the plastic hinge of ...
